Molex Inc.'s SST DN4 DeviceNet USB interface module provides industrial OEMs and end users with a compact, high-performance DeviceNet interface for PC communication that is said to maximize performance in control and monitoring applications. Like the SST DN4 NICs, the USB interface module uses an enhanced FPGA design with a lower component count, resulting in an extended product life cycle and higher reliability. Suitable for real-time control and data-acquisition applications, which range from PC control and HMI/SCADA systems to network configuration, troubleshooting, and diagnostic tools. Simultaneous execution of Group 2 Client (master) and Server (slave) operations allows the implementation of control schemes where all capabilities may be required. Suitable for any DeviceNet control scheme, the DN4 supports poll, strobe, change-of-state (COS), and cyclic input/output messaging. The QuickConnect capability of the USB interface module in client (master) mode allows the devices to be accessed on power-up in less than 500 ms.
